Cross-Connection Inspections- Hydro Corp

A cross-connection is an actual or potential connection between the safe drinking water (potable) supply and a source of contamination or pollution.  State plumbing codes require approved backflow prevention methods to be installed at every point of potable water connection and use. Cross-Connections must be properly protected or eliminated. 

For the past few years HydroCorp has been contracted by the City to assist with our Cross-connection Control (CCC) Program. The CCC program includes two parts: On site inspections and testing of backflow prevention assemblies. The HydroCorp inspector will be conducting a visual inspection of the water uses outside of your home (outside spigots, lawn irrigation system, secondary sources of water, pools, etc.) to identify cross-connections that could possibly contaminate your drinking water or the public water supply.

If Rhinelander Utility requires an inspector to enter your home to evaluate other cross-connection and plumbing hazards inside your residence, you will be notified and instructed to schedule an appointment for your inspection. All water customers (residential and nonresidential) connected to the public water supply are required to be inspected for cross-connections. Inspections take 10-20 min.

Our program strives to ensure that all water customers receive an initial inspection during the first 3-5 years of program implementation. If you are the owner of the home being inspected, you are responsible for any needed repairs. Renters may have to refer to their lease agreements in order to determine whether they are responsible for repairs.
